In parallel circuits, what relationship exists between flow in each branch?

In parallel circuits, the key characteristic is that each branch can have different flow rates while maintaining equal pressure across them. This means that although the flow in each branch may vary depending on the resistance and other factors, the pressure drop across each branch remains constant due to the nature of parallel circuits.

The flow through each branch is influenced by the respective resistance of that branch; thus, each branch can carry a different flow rate. However, the overall pressure drop across the entire circuit is the same across all branches, aligning with the fundamental principles of parallel flow systems.

Therefore, understanding this behavior is crucial for designing plumbing systems effectively, as it helps to predict how changes in one branch will affect the overall system while maintaining constant pressure across the feed to each branch.
